LUBRICAITT-NEBULIZER.

Patented Mar. 10, 1914. Serial No. 747,764.

To all whom it may concern Be it known that I, BENJAMIN F. How- Ann, acitizen of the United States, residing at Indianapolis. in the county ofMarion and State ot Indiana, have invented certain new and usefulImprovements in Lubricant-Nebulizers, of which the following is aspecifica-tion.

The object of this invention is to mix a regulated quantity oflubricating oil with an auxiliary supply of steam, and then to dischargethe mixture into a main pipe which supplies steam to the cylinder of asteam motor; and the object more particularly is to utilize the heat ofthe auxiliary steam supply to vaporize the oil, and then to bring theoil vapors and steam into direct contact with each other preliminary tomore thoroughly nebuliziug the vapors by discharging them through anozzle into the main steam supply pipe.

I accomplish the objects of my invention by the mechanism illustrated inthe accompanying drawing, in whichk Figure 1 is an elevation and partialvertical section of a main steam pipe and a lubricator, with myinvention applied in operative relation thereto. Fig. 2 is a verticalsection on the line 2 2 of Fig. 1, and Fig. 3 is a horizontal section outhe line 3-3 of Fig. 1, the arrows indicating in both sections thedirection of view.

Like characters of reference indicate like parts throughout the severalviews of the drawing.

1 is the main steam supply pipe through which live steam is conveyed inthe direction of the arrows shown in said pipe to the cylinder of asteam motor (not shown).

2 is an oil container' into which a pipe 3 from a steam condenser 4lextends to near the bottom of the container 2. The condenser 4l isconnected by a branch pipe 5 with the main steam supply pipe 1.

6 is a valve in pipe 5 for regulating the discharge oi steam through it.

The height of the oil in the container is shown by a glass gage 7, andon the other side of the container is a stand pipe C, preferably ofglass, which communicates at its lower end with the container 2, nearthe bottom of the container 2. The stand pipe 8 discharges at its upperend into a horizontal pipe 9 and the pipe 8 is filled with water,glycerin, or the like, to which oil globules coming from the container 2are floated to the level of the pipe 9, and the oil thus delivered inregulated quantities to the pipe 9 is conducted by the latter to auimderside discharge opening 10. The openlng 10 is preferablycountersunk, as shown, to better collect the lubricating oil fordischarge through the discharge opening 10. A drill hole in thediametrically opposite upper wall of the pipe 9, normally closed by ascrew plug 11, affords means for the initial formation ot' the dischargeopening 10, and also means for cleaning out the opening' should itbecome clogged.

Surrounding the pipe 9 between thereontainer 2 and discharge opening 10is an annular chamber 12 (see Fig. 2), through which steam deliveredfrom the branch pipe 5 through an auxiliary pipe 13 circulates. Theannular chamber 12 discharges at its bottom into a chamber 14 extendinghorizontally under the pipe 9 in the direction of the main pipe 1, andseparated from the pipe 9 by a common wall through which the dischargeopening 10 is formed. The hot steam coming through the auxiliary pipe 13and passing around the pipe 9 through chamber 12, and also filling andpassing through the chamber 14, heats the pipe 9 and volatilizes thelubricating oil in the latter, causing it to discharge 1n a vaporthrough the opening 10 into the chamber 14v where it mixes with thesteam in said chain ber 141-.

An extension 15 of the chamber 10 projects through the wall of the mainpipe 1, an appreciable distance into the pipe 1. The chamber 14 andextension 15 are in two transversely divided parts which are united bymeans of a coupling 1G, and the chamber 10 also terminates in a nozzleextension 17, located within the chamber extension 15. The steamdelivered under pressure to the chamber 14, and there mixed with thevaporized lubricant, as above described, is discharged with its burdenoi oil through the nozzle 17 and t-he mixture .is thereby morethoroughly nebulized and blended.

The liointed construction united by coupling 16 allows the parts to betaken apart at the joints for greater convenience in manufacture and forconvenience in cleaning out or changing the nozzle. In practice thenozzle 17 is made as ,a detachable part.

The auxiliary pipe 13 is in a plurality of transversely divided parts,secured by means of a coupling 18, which construction allows for thedisconnection of the pipe for convenient renewal and cleanout purposes.The auxiliary pipe 13 is provided with the valve 19.

It will be observed that my invention is constructed so as to be readilyapplicable to use with lubricators now in common use for the purpose ofrendering the latter more economical and efficient in the supply oflubricants.

While I have described my invention with more or less minuteness asregards details of construction and arrangement and as being embodied incertain precise forms, I do not desire to be limited thereto unduly orany more than is pointed out in the claims. On the contrary, Icontemplate all proper changes in form, construction and arrangement,the omission of immaterial elements and the substitution of equivalentsas circumstances may suggest or necessity render expedient.

I claim:

l. The combination with a main steam pipe of a mixing chamber in twotransversely separable parts discharging into said pipe, an oil supplypipe discharging into said mixing chamber, means Jfor supplying oil indrops to said pipe, a steam chamber through which the oil supply pipepasses, an auxiliary pipe supplying steam to said cham- A ber, saidsteam chamber discharging into said mixing chamber.

one joint being `.this 6th day of February, sand nine hundred andthirteen.

2. The combination with a main steam pipe of a mixing chamber in twotransversely separable parts discharging into said pipe, a nozzle insaid chamber at the joint between said two parts, an oil supply pipedischarging into said mixing chamber, means for supplying oil in dropsto said pipe, a steam chamber through w ich the oil supply pipe passes,an auxiliary pipe supplying steam to said chamber, said steamdischarging into said mixing chamber.

3. The combination with a main steam pipe of a mixing chamberdischarging into said pipe, said mixing chamber being in twotransversely separable parts, a nozzle in said chamber at the ]ointbetween the two parts discharging toward the main steam pipe, an oilsupply pipe discharging into said mixing chamber through a reducedopening in the lower wall between the oil supply pipe and mixingchamber, means for supplying oil in drops to said oil supply pipe, asteam chamber through which the oil supply pipe passes to volatilize theoil, and an auxiliary pipe supplying steam to said chamber, said steamchamber discharging into said mixing chamber.

In witness whereof, I have hereunto set my hand and seal atIndianapolis, Indiana,
